Circling back around to this...
If you want this done you have to basically demand it from an orthopedist. They do a 3 min CT scan called a "scout" which cost me just over $100. The radiologist had the images read that afternoon. I was told it is not a very common scan so only certain places do it.
For those curious no I don't have an LLD but to my amateur eyes my pelvis looks twisted and my spine looks very mildly scoliotic. Pelvis looks way more jacked up than spine but I was lying down so maybe that changes things.
Going to schedule another appt with ortho.
